what is a clanker?
Clanker meaning, where the word came from, and how the clanker test works.
Clanker is internet slang — borrowed from Star Wars — for a robot or an AI. In 2025 it went mainstream as a jab at anything that sounds machine-made, including AI-generated writing. To be clanker is to be predictable: to write the words a language model would have picked anyway.
the clanker test
This site is a reverse Turing test. Instead of asking whether a machine can pass for human, it asks how human you sound to the machines. Drop an @handle to grade someone's recent posts, or finish five sentences to diagnose your own writing. Each word is scored by its surprisal under Llama, DeepSeek and Qwen — how much the model expected it. Low surprise means low information means clanker.
faq
- What does “clanker” mean?
- Slang for a robot or AI, borrowed from Star Wars. Online in 2025 it became shorthand for anything that sounds machine-made — including AI-generated text. To call writing clanker is to say it reads like a language model wrote it.
- Where does the word clanker come from?
- It's Star Wars slang for battle droids, named for the clanking of their metal bodies, and it turns up in sci-fi as far back as the 1950s. In 2025 it jumped to the real world as anti-AI slang aimed at chatbots, delivery robots and AI writing.
- Am I a clanker?
- Take the test to find out. If your writing is highly predictable to language models — low surprisal — you score high. Em-dashes, the word “delve”, tidy parallelism and constant hedging all read clanker.
- Is the clanker test an AI writing detector?
- Sort of — flipped, and for fun. Conventional AI detectors give a binary AI-or-not verdict; the clanker test measures a spectrum of how AI-like writing reads, using the models' own next-token probabilities. It's a toy, not a judgment.
- How is the clanker score calculated?
- Every word is scored by its surprisal — negative log probability — under each model given your text so far, across Llama, DeepSeek and Qwen. Lower surprise means more predictable means more clanker; your overall is your nearest, least-surprised model.
- What is a cogsucker?
- Related anti-AI slang for a human who's a little too fond of the machines. If a clanker is the robot, a cogsucker is its human apologist.
